There are few things we Americans do that can truly be described as “national”. There’s Thanksgiving, the Super Bowl and, every four years, we elect a president. Sure, voters use a variety of criteria to select their favorite candidates. But it’s arguable that at heart the presidential election is a contest over whom we want to represent not just our nation but our idea of nationhood and who we are as a people.（1）.One way voters decide who we are as a nation is to decide who we are not. Remember what your high school civics teacher taught you? Your rights end right where someone else’s begin. （2）. The very act of asserting an identity involves distinguishing yourself. In politics, it sometimes involves delegitimizing （使失去合法或合理性）the opponent.（3）. Obama is trying to broaden our collective notion of the mainstream. On the one hand，his campaign is running television commercials in Iowa featuring his late mother, who was white. On the other，he touts his biracial, multicultural background as an advantage when it comes to representing the U. S. abroad.In another, not so distant, era, a white candidate like Hillary Clinton could simply have used race as a way to portray her black opponent as being beyond the mainstream.（4）. Instead，some elements of the Clinton campaign have seized on Obama’s ancestral ties to Islam --- the Illinois senator is a Christian and Americans’ wariness of the Muslim world as a way to associate him with something outside of “who we are as a nation”，a way to delegitimize his campaign to represent all Americans.Should all of this come as some sort of shock? No.（5）. But during this primary season，just remember you’re not only selecting your party’s presidential nominee. You’re also, in no small sense，being asked to decide, in national terms, who’s in and who’s out.
